Hi guys.
Currently using the ERA homeguard alarm which works pretty well. However id like to protect my garden from intruders as well as my home.
My original idea was to use those cheap chinese duel beam ir laser sensors with the relay output replacing the reed switch on the magnetic door contacts from the ERA alarm, sort of a hack so i can use the laser sensors with my current alarm system.
I have used these dual beam things at my previous house and they worked great, however at this house there is no way i can avoid placing them in direct sunlight and they will have to be placed on walls with the beam running parallel (instructions say to have it mounted 1m away from a parallel wall), it doesnt look like ill be able to use them.
I want to protect 3 areas...
1: garden wall so the alarm trips of someone climbs over.
2: across the bottom of the garden behind the garage.
3: across my patio incase somebody approaches my the rear of my house.
Anybody have any ideas as to what else to use rather than the ir lasers? Or perhaps a way to still use the ir lasers even in sunlight and so close to a wall?
PIR is out because the dog has free roam when im not at home and the garden wall is low so would pick up the neighbours.
A tricky one i know.
Many thanks.
